x86_64: various cleanups in NUMA scan node
In acpi_scan_nodes(), we immediately return -1 if acpi_numa <= 0, meaning we haven't detected any underlying ACPI topology or we have explicitly disabled its use from the command-line with numa=noacpi. acpi_table_print_srat_entry() and acpi_table_parse_srat() are only referenced within drivers/acpi/numa.c, so we can mark them as static and remove their prototypes from the header file. Likewise, pxm_to_node_map[] and node_to_pxm_map[] are only used within drivers/acpi/numa.c, so we mark them as static and remove their externs from the header file. The automatic 'result' variable is unused in acpi_numa_init(), so it's removed.
